Experimental Study on Two-phase Flow in Artificial Hydrate-bearing Sediments

It is important to investigate gas-water multi-phase flow in methane hydrate-bearing sediment. In this work, we measured relative permeability of gas and water in artificial methane hydrate bearing sediment by the unsteady state method, and determined the effects of hydrate saturation on relative permeability curves. The results show that the relative permeability shifted left with increasing hydrate saturation.
